text: There will be an impeding event that could occur which is water in the water bath being drawn inside the can by the reduced pressure. As a result, in a basic demonstration, only an aluminum can is able to be used since it is not very strong. Unlike other stronger can such as steel can, the aluminum can will be collapsed before the water can be drawn inside the can. Nevertheless, Professor Julius Sumner Miller could make a steel drum collapse by sealing the opening of the drum after the water inside the drum boils and pouring water and ice onto the drum surface.
